# Science fiction operates as descriptive mythology that explores present anxieties through future framing rather than literal prediction

Ursula K. Le Guin's canonical framing: 'Science fiction is not predictive; it is descriptive.' Ken Liu demonstrates this through systematic prediction failures: flying cars predicted for a century but absent from everyday life; 1899 French artists imagined cleaning robots needing human operators (fundamentally different from autonomous Roombas); Year 2000 killer robots and Jupiter missions never materialized. Liu argues SF crafts 'evocative metaphors' that persist culturally even when technical details are wrong, operating as 'descriptive mythology' that explores the anxieties and possibilities of its PRESENT moment. This reframes the fiction-to-reality pipeline: rather than commissioning future technologies, SF provides a cultural space for societies to process contemporary tensions through future scenarios. The persistence of certain SF concepts reflects their resonance with present concerns, not their predictive accuracy.
